The International TD-20B replaced the TD-20 Series 201. A new 429 ci turbocharged 6-cylinder diesel, similar in design to the 361 ci of the TD-15B, replaced the 691 ci engine of the old TD-20 Series 201. The International DT-429 engine was rated at 150 net hp initially and increased to 160-hp in 1965. A 4-speed partial power shift transmission (2-speed power shift combined with 2-speed manual and torque converter) replaced the old manual 6-speed.
In 1963 the 150-hp International TD-20B, with its small high-speed turbocharged engine, was equal in power to the Allis-Chalmers HD-16 with its big low-speed non-turbo engine but the International was 10 hp behind the Caterpillar D-7E. International went to 160 hp in 1965 but the new power shift Allis-Chalmers HD-16DP jumped to 170 hp and Caterpillar went to 180 hp in 1966.
